O Working Days é um aplicativo que permite facilmente calcular um intervalo entre duas datas no Brasil. Além de dias úteis, que é o nome do app ;P, podem ser calculados: dias corridos, semanas, meses, anos e horas trabalhadas (quando informado o número de horas trabalhadas por dia últil). Com os ícones de cadeado disponíveis na interface, pode-se bloquear rapidamente a data inicial ou final, para facilmente aumentar ou diminuir o intervalo de datas a ser calculado. O processo de cálculo é executado automaticamente a cada interação com o aplicativo, ex.: quando se aumenta o número de dias úteis, as datas de início e fim se modificam de acordo com o bloqueio utilizado (cadeado). Outra funcionalidade presente em nosso aplicativo é a capacidade de listar feriados que ocorrerão neste intervalo e também filtrar os feriados específicos de cada estado. O app atualiza sua lista de feriados a partir de dados disponíveis em nosso cloud, contando sempre com dados atuais. Eventos especiais (Dia das Mães, Dia das Crianças, ...) também ficam listados caso o usuário habilitar essa opção no menu de configuração do aplicativo. Estamos constantemente atualizando os feriados nacionais e regionais, fique a vontade em contribuir, nos enviando os feriados regionais de seu estado.
